You all know the good old Quartermaiden. You all know Stonescar Gunslingers. This deck, is both.
Wyatt, Junk Collector is pretty useful since he allows you to swap power you don't need for potentially better cards. He also becomes pretty good if you equip him with
Thief's Pick or
Longbarrel, since he's almost certain to trigger his ability this way. (expecially turn 3)
If you ever get into a lategame boardstall, grab your
Kaleb, Uncrowned Prince from the Market.
Jekk, Lone Gun is also a pretty useful asset in the later game. If none of your Wyatts connect 3 times, a backup
Smuggler's Stash can also be grabbed with
Ixtun Merchant.
Vicious Highwayman and
Champion of Chaos in the Market are just in case you really need a Gunslinger for
Hideout Pistol and/or to finish up the game. One of them may be replaced with a
Bore in the Market.
I guess the rest of the deck speaks for itself, go ahead and give it a go.
